SiliaPrep Tips Micro-SPE Cartridges

SiliaPrep Tips for Micro Sample Preparation

SiliaPrep Tips Micro-SPE Cartridges are designed for micro-purification and micro-extraction of femtomole (fmol) to picomole (pmol) quantities of analytes prior to the analysis by chromatographic techniques and / or mass spectrometry.

The constant improvement in these techniques of analysis has allowed scientists to decrease the limit of quantification in several applications. This lower limit has pushed SPE manufacturers to design new SPE cartridges accepting smaller volumes of analyte.

These tips are specially designed to achieve extraction and purification of small molecules, peptides, phosphopeptides and proteins.
They are packed with our SiliaBond functionalized silica gels and specialty phases to cover the broadest spectrum of applications requiring small volume of analytes.

The phases are embedded directly in the inner surface of the tip to provide consistent flow rates. Finally, no glue is used during packing procedures in order to prevent any contamination of the analyte.

Using SiliaPrep Tips and Tips Micro-SPE Cartridges guarantees the following benefits:

Simple, fast analyte retention & elution with minimal loss

Sorbents directly embedded into inner cartridge wall

High binding capacity

No back-pressure
